If you could install a game, like a real official DS/DSi cartridge game. You install it so you never have to take the game out again, only you HAVE to have the official cartridge so no ROMs can be downloaded and installed. Also, the games can only be installed once, but the saves can be updated from the cartridge and the 3DS.

Or they wipe the cartridge so you can't play on both and put the data on the 3DS. Then if you want your cartridge back, put the "blank" one back in and install the save again (removing it from the 3DS memory)

IDK, like my idea?

 

It's possible. Doesn't XBOX 360 do this? You can put games onto the HDD so they load faster but you have to have the disk in to play them.

 

The xbox 360 and ps3 both have this feature

 

I thought Nintendo had already confirmed that you could back up and play your games, seeing as it looks like they're trying to fulfill at least most of the reasons people use flashcarts in the first place on the DS

 

If the 3DS supports SDXC, the cards can go easily around 2TB. That'd be about enough for the whole DS generation of games. Thus the 2-8gb games would be nothing in comparison. Otherwise the 32gb MicroSD would help most gamers if this option was available..

It would be pretty difficult to explain to customers that they need to buy an additional SDXC card in order to install games > 2 Gb...

 

DS carts are 98% ROM, 2% RAWM (i made that up, i forget what it's really called).
The game itself is on ROM which means it's not erasable, editable, etc.
The save for your game is on the RAWM, which can be written to, and read obviously.

On your idea as a whole: I doubt it.

 

If I were Nintendo adding this sort of option, I would have it so that each game would have to be registered to you account to be allowed to install the game, only allow to install on one 3DS, during the install, contact the Nintendo servers to check that that cart is registered to that account. Once that is done, periodically check that the user still owns that cart by refusing to run the backup after a couple of weeks or a month, unless that cart is inserted and checked against the server. If a different user tries to install on their system, have the original user contacted, if no contact is made with x amount of time, transfer the licence to the new user.
